Eng.) - Asian Institute of Technology, 1996  aPlastic injection molding is one of the most important methods of manufacturing  plastic products. The injection mold is the heart of the injection molding process. The quality  of the injection products and the economics of the process are critically influenced by the  designers' skill and prevailing technological conditions. This study was conducted to develop  a computer-aided design methodology that design engineers could use to design injection  molds for small and medium mold shops. In order to optimal product and mold design,  existing and new methods are developed for mold flow analysis based on the standard  facilities available in CAD/CAM systems. These are cooling time calculation, flow front  design, temperature calculation on each flow front and cooling channel design for achieving  optimal mold design. These methods can serve as bench mark to test existing injection mold  design and to optimize design. The methodology developed was used in a case study  concerning the designing of a bottle carrier injection mold based on the general design  considerations and flow fronts analysis without the use of mold flow software. The designed  mold is tested by using C-FLOW simulation software to simulate the flow in the cavity and to  get optimal molding processing conditions. The designed filling image is compared with the  results of C-FLOW analysis and the conclusion shows that the designed mold is optimal.  10aComputer-aided design1 aBohez, Erik L.J.,eChairperson1 aDuflou, Joost R.,eExamination committee1 aPandey, P.
